a specification.

The invention relates to a swivel chute-head for apparatus for handling material in bulk.

The object of the present invention is to provide for apparatus for handling material in bulk a swivel chute-head adapted to permit a superimposed chute to be swung upward and downward and capable of enabling the same to be rotated or swung horizontally, whereby the chute may be readily arranged in proper position for discharging the material.

A further object of the invention is to permit such adjustments of a chute without allowing any of the material to escape at the chute-head or joint between the chute and its support.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a chute having a swivel chute-head constructed in accordance with this invention. Fig. 2 is an enlarged vertical sectional view of the upper end or head of the chute. Fig. 3 is a horizontal sectional view on the line3 3 of Fig. 2. Fig. l is a vertical sectional view, similar to Fig. 2, illustrating another form of the invention. "Fig. 5 is a horizontal sectional view on liner) 5 of Fig. 4:. Fig. 6 is a detail view illustrating the arrangement of the antifriction-rollers with relation to the curved guide. Fig. 7 is a detail sectional view on line 7 7 of Fig. 3.

Like numerals of reference designate corresponding parts in all the figures of the drawm s.

1 15 designates a depending extensible chute adapted to swing vertically and horizontally and preferably composed of upper, lower, and intermediate sections 182, 183, and 184;, which are adapted to slide or telescope to vary the length of the chute. The upper section 182 of the chute is provided with an enlarged end or top 182, tapering downwardly and pivotally connected by the means hereinafter described with a rotary bearin g-sleeve 17 4, which is mounted on a supporting-neck173. The annular supporting-neck 173 is provided with an upper attachment-flange 173 and it has a lower bearing flange 173", and the upper flange 173 is perforated for the reception of bolts or other suitable fastening devices for securing the neck 173 to the support for the chute. Thelowerbearing-flange173 extends outward from the exterior of the neck 173 and is provided at its upper face with an annular groove forming a race for antifriction-balls 173, which enable the bearing-sleeve 174 to rotate frictionlessly on the supporting-neck 173. The bearing-sleeve 174 is composed of upper and lower rings 174 and 17 1 and the ring 174: is also composed of semicircular sections provided at their ends with abutting flanges 174 which are bolted or otherwise secured together, as clearly illustrated in Fig. 3 of the accompanying drawings. The up per bearing-ring 174. is'arranged above the bearing-flange 173 of the supporting-neck 173, and it rests upon the antifriction-balls and extends outward beyond the same. The projecting portion of the upper bearing ring 174: is secured to the lower ring 174: by an annular series of bolts 174 or other suitable fastening devices arranged as clearly illustrated in Fig. 3. The lower ring 174: has

a contracted lower portion and is provided with a depending inner chute-section 175, extending downward into theenlarged upper end of the upper chute-section 182 and adapted to prevent the escape of material when the said chute-section 182 is in any position. The inner chutesection, which is tapering and which is disposed vertically, may be constructed separate from the lower ring, as illustrated in Fig. 2 of the accompanying drawings, or it may be formed integral, as hereinafter explained in connection with Fig. 4:, and it is adapted to permit the chute 115 to swing on its pivot in either direction as far as possible without any liabilityof the material escaping through the chute head or connection. The lower ring is provided at opposite sides with tubular extensions 1745*, adapted to register with corresponding tubular extensions 182 of the upper section 182 of the chute, and

these tubular extensions form eyes for the reception of pivots or pintles 176 on which the chute swings. The eyes or tubular extensions of the ring are preferably formed integral therewith, and the eyes or bearings 182 are preferably formed integral with plates 182, which are riveted or otherwise secured to the enlarged upper end of the upper section 182 of the chute. The pivots, which are provided at their inner ends with heads, have suitable fastening devices at their outer ends for retaining them in alined eyes of the lower ring and the upper chute-section 182. By this construction the chute is pivoted to the bearing-sleeve at opposite sides thereof and the said bearing-sleeve is adapted to rotate on the supporting-neck. These movements will permit the chute to swing vertically and horizontally, whereby it may be arranged in the proper position for discharging the material handled.

In Figs. 4 to 6, inclusive, of the accompanying drawings is illustrated another form or modification of the invention in which a depending neck 177 is employed, and this depending neck is provided with an upper attachment-flange 178, and it has a lower bearing-flange 179, located between the upper and lower edges of the neck and provided at its upper, lower, and side faces with annular grooves forming ball-races for antifrictionballs 180, interposed between the bearingfiange and a bearing-sleeve 181. The bearing-sleeve 181 is composed of upper and lower bearing-rings 183 and 184 and the upper bearing-ring is sectional and is provided at the ends of its sections 185 with abutting flanges which are bolted or otherwise secured together, as clearly illustrated in Fig. 5 of the drawings. By constructing the upper bearing-ring of sections the bearing-sleeve is readily interlocked with the bearing-flange of the depending neck and the parts may be readily assembled. The lower bearing-ring of the bearing-sleeve is provided with a pair of rearwardly-extending eyes 186, located at opposite sides of the bearing-sleeve and receiving av continuous pivot or pintle 187*, which extends beyond the eyes 186 into a pair of eyes 188, formed integral with plates 189 which are secured to an upper chute section 190, as clearly shown in Fig. 5. The bores of the eyes 188 of the upper chute-section are arranged opposite apertures or openings of the latter, and the pivot or pintle is retained in place by set-screws 191, mounted in threaded perforations of the rearwardlyextending ears and engaging the pivot or pintle. The bearing-sleeve is provided with an inner taperingchute-section 192 depending from and formed integral with the lower bearing-ring and provided at its front side with a curved guide 193, consisting of a skeleton frame having a curved outer edge struck on an arc of which the pivot 187 is the center. The guide is provided at opposite sides with laterally-extending webs or flanges 194, located between a pair of anti friction rollers or wheels 195 -and provided at its top with a head 196, forminglaterallyextending stops arranged to be engaged by the antifriction rollers or wheels, as clearly illustrated in Fig. 6 of the accompanying drawings, when the upper section of the chute is at the limit of its movement in one direction and the guide is provided at its bottom with a suitable stop for limiting the movement of the chute in the opposite direction. The antifriction rollers or wheels 195 are mounted on the inner face of the upper section 190 of the chute and are located at the upper edge of the same, and they permit the chute to move freely and frictionlessly. The guide supports the chute and prevents the same from moving laterally and straining the pivot.

The chuteis controlled by suitable ropes or cables designed to be operated by a winch (not shown) and connected with a boom 177, which is hinged at its inner end. A pair of booms are designed to be provided and are located at opposite sides of the upper end of the chute, as indicated in Fig. 2 of the accompanying drawings, suitable brackets 197 being provided for supporting the booms. The telescoping or sliding movement of the sections is controlled by a rope or cable 185, secured at one end to the upper section of the chute and extending longitudinally of the latter to a pulley 186 and passing therefrom rearwardly along the chute to a pulley 187. The pulley 186 is mounted on the lower section of the chute, and it will be apparent that by drawing in the cable or line 185 and by paying the same out the chute may be shortened or lengthened. The intermediate and lower sections of the chute are connected with the boom by means of ropes or cables 189 and 190. The rope or cable 189 is secured at one end to the boom at a point intermediate of the ends thereof, and it extends downward to the intermediate section and back to the boom, forming a supporting-loop, which is connected with the intermediate section 184c by a suitable block having a pulley. The other rope or cable 190 is arranged at the outer end of the boom and is connected in a similar manner with the lower or bottom section 183, and by drawing in the ropes or lines 189 and 190 and paying them out it will be clear that the chute may be swung upward and downward to arrange it at the desired elevation. I

It will be apparent that the construction for supporting the depending chute is simple and comparatively inexpensive in construction, that it will permit the chute to be swung vertically and horizontally to arrange the same in the desired position, and that it will prevent the material from escaping at the top of the chute when the latter is in any position.
